Speed Abs Complete Ab Workout System

First off, I've no idea why a few reviews said assembly was hard or confusing. It's literally a wheel and 2 handles. The handles of which ONLY can be installed one way on either side. It literally took me longer to open the box than assemble the thing AND do a quick workout. And all this was before I even noticed the instructions in the box.The unit is well built. The handles are actually quite comfortable, made of a hard plastic rather than cloth or rubber. So you don't have to worry about any material rubbing off after a bit of use. The spring in the return system is adequate. It's strong enough to assist with your work out, but not too strong where it's doing the work for you. I've tried various ab workout wheels. This wheel does emit some noise from the spring coiling and releasing, but it's right in line with other units I've tried. But of course, your focus is working out, not silence. Though the sound is pretty subtle.In all, very nice product. My only gripe is that I wish the wheel was more omnidirectional. The spring will ONLY work in one direction. So if you turn the wheel backwards, the spring will not allow you to use the machine, and you'll likely end up breaking the unit. There is an arrow depicting the direction of which the wheel is supposed to go. But it is a bit annoying to attempt to start working out only to discover you're turning the wheel backwards and it's not letting you move.Good unit. Will update this review as needed.
